To all, whont it Indy concern: 9

Be itknown that I, EWELL H. MURFHY, a

citizen of the United States, residing at Italy,

in the county of Ellis and State of Texas, have invented certain new anduseful Improvements in Painters Elevators, of which the following is aspecification.

My invention relates to improvements in elevators, and more especiallyto painters elevators, and has for its object to provide a device whichis exceedingly simple and inexpensive in construction and easy tooperate,

designed for use in painting the exterior walls of houses or otherstructures,for the elevation of materials duringthe construction ofbuildings, and also for use as a fire-escape.

My invention consists in an elevator having a frame provided With aslidable platform and operating'device for adjusting and holding saidplatform'at different points on said frame, said operating device beingwithin convenient reach of the operator, so that he sired point withoutdescending to the ground or requiring the assistance of otherpersons.

It also consists in the construction, comhination, and arrangement ofthe several parts, as more fully hereinafter described and claimed.

My invention is illustrated in the accompa-' nyin g drawing, whichrepresents a perspective view of my improved painters elevator.

Referring to the drawing, in which like numerals of reference denotelike parts, 1 represents the frame of the elevator, whichis.

made of a height to correspond substantially with the height it isdesigned to elevate the slidable platform, and comprises a base 2,upright sidepieces 3 4, secured at their lower ends to said base 2, topcross-piece 5, secured to and connecting the tops of the side pieces, aseries of diagonally-arranged cross-braces 6 between said side piecesfor the purpose of strengthening and bracing the frame, braces 7 on theoutside of the frame, one end of each secured to one of the sidepiecesand the.op posite end of each to the base 2. The frame of the elevatoris leveled when the ground or other surface onwhich said frame rests isuneven by adjustable blocks 8,

which comprise a base 9, and a vertical post lO, preferablysquare incross-section and pro-: vided with a series of holes 11. Y The posts ofsaid blocks are adapted, to be inserted in holes 12 in the oppositeouter ends of said base '2, and after being adjusted therein to thedesired point are securely held by means of pins and then through oneofthe series of holes 11 in. the posts 10. I

"The frame of the elevator is keptin an upright position bymeans ofabrace 15, one end .of which is secured to a cross-rod pivoted at apoint 17 in each of the side pieces 3 4, and. the opposite end ispointed andjnserted-into the ground. Y 1

arms Wlfll'i, attache t side pieces of theframe near are provided withpointed endsl Acrossrod 19* connects said arms together adjacent theirpointed ends. The arms 18 are adapted to project against the side of'the'wall of a building and keep the'frame of the elevator a sufficientdistance from the said wall to allow the slidable platform hereinafterdescribed to freely operate. I

20's a vertically-slidable platform mounted on a pair of brackets 21,each comprising a horizontal arm 22, provided with a loop 23"", whichembraces one of the side pieces, and

'wardly and outwardly extendingarm 25, provided with a loop :23,embracing one of the side pieces and having a wheel 26 mounted therein,an arched cross-bar 27, connected at its opposite ends to the inner sideof the arms 25 and at its center to the under surface of the platform.20, and vertical bars 28, which are connected at their opposite ends tothe outside of the arms .25. An inverted- U- =shaped bracket 29 is seenred to theupper surface of the platform 20 near its outer edge and has asingle-pulley wheel 30, mounted therein. A double-pulley block 31 issusthe platform 20 at any convenient point, preferablyjust at pneside ofthe bracket 29, and comprises a base portion 33, an upwardly extendingarm 34, which is provided with 13, which are inserted in holes 14in thebase.

the top and extend rearwardly therefrom and having a wheel 24 mountedthe'reon,.a downpended from the top cross-piece 5 of the frame.

A rope clamp or retainer 32 is secured to 18 represents pairofhorizontally-disposed re bolted or otherwise suitably 2 arm 34 and thatportion of the rope previously notches 35 and 36, diagonally arranged onits opposite edges and the top turned over and formed into a hook 37',

One end of'a rope or cable 38 is'fastened to the bracket 29, then theother end run over one of the wheels of the double-pulley-block 31, overthe single-pulley wheel 30, then over the other wheel of thedouble-pulley block, and finally passed under the hook 37 of therope-clamp through the slots 35 and 36, then back again into the hookand between the inserted inthe hook, and thus the end of the rope willbe'firmly clamped and the slidable platform held at any desired point orelevation.

In operating the elevator is placed in the desired position in relationto the wall of a v house or other structure with the pointed ends of thearms 18 engaging the said walls and the brace 15 firmly secured in theground. Then to operate the elevator it is only necessary to mount theplatform and pull on the rope 38 until the platform has reached the.

ets and cross-bar, and means for adjusting and holding said platform atdiiferent elevations on saidframe, substantially as described; v

2. An elevator provided with a frame having'pulley-wheels, a slidableplatform'having a bracket rope, one end attached to said bracket andrunning over the pulley-wheels, and a clamp for holding the other end ofsaid rope mounted on said platform comprising an upright arm havingnotches on its opposite edges and a hook'at the top, substantially asdescribed.

3. 'An elevator provided with a frame, hav ing a double wheel-pulley, aslidable platform having a bracket provided with a pulley-Wheel, a rope,one end attached to the bracket and running over the pulley-wheels, anda clamp for holding the other end of said rope mounted on said platformand comprising a base, an arm extending upwardly therefrom havingnotches arranged diagonally of each other on its opposite edges and ahook at the top, substantially as described.

4 An elevator provided with a slidable platform adapted to be elevatedby means of a rope or cable, and a clamp on said platform for holdingthe end of the rope comprising an upwardly-extending arm having notchesin its opposite edges and its top provided with a hook, substantially asdescribed.
